http://www.ctci.org/gilsgarage/ValveGapperInstructions.phpI too remember them. Would make a solid lifter engine sound as a well tuned sewing machine when all valves were perfectly dialed in. The best solution for worn rockers.
A bit messy with engine running. In those days, did not seem as big a deal as now.
Don't know if had a kit for Hemi engines. Each engine required proper adapters.
Would be just the ticket for our 300 B.. However must pull generator/power steering pump combination to remove driver side valve cover,,,then re-install to start engine for adjustment of valves with engine running,,,could skip this re-install I suppose and idle engine with belts(there are 2 on dual groove generator/PS pulley) left off.

. For a .032" gap if a .031" feeler gauge has no drag and a .033" gauge has a slight drag that is as close as you can get (with feeler gauges). A dial indicator type gapper would be the best & reportedly a few tho difference in the gap has a significant impact on changing valve timing but this was decades ago & iirc it was in conjunction with an ad for a P&G valve gapper which is a dial indicator type valve gapper
